Application filed June 7, 1922. Serial N0. 566,623.

To all whom it may concern:

Be it known that I, GUSTAV Anonrii HU nnn, acitizenof the United States, and resiv dent of Landing,-in the county of Morris and State of New Jersey, have invented certain new and useful,Improvements in an Electric Bell, of whichthe following is aspeci-fication.

This invention relates to an electric bell. Its object is the production of a bell that is composed of but few parts, and which is provided with a clapper that can be rapidly reciprocated to strike a gong. A second object of the invention is the production of an electric bell provided with a gong, that covers the movable elements thereof to'protect them. 7 V

Other objects will be 4 evident from the following description and claims.

Fig. 1 represents afront view of the electric hell with the gong thereofremoved; Fig. 2 shows a rear-view of Fig. 1 ;Fig. 3 indicates a top plan view of Fig. 1, with the gong thereof in axial horizontal section; Fig.

represents a left handside view of Fig.1

with the gong thereof in vertical axial section; Fig. 5 shows a left hand side viewiof Fig. 1 with the gong thereof in "vertical axial section; Flg. 6 represents anelevation of an armature; Fig. 7 is a top plan view of Fig. 6; Fig. 8 shows a left hand side view of Fig. 6 and'Fig. 9 shows the bell with a wiring diagram.

A frame is indicated in its entirety by the letterA and comprises the front Wall QOf from which rearwardly extends the flange 2-1. The wall 20 has formed thereinthe central longitudinal opening 22, and in this instance has pressed out therefrom the out- 1 wardly extending guide lug 23 forming the opening 241 in the wall 20.

A guide lug 28 with the guide opening 29,

is also pressed out from the wall 20, leaving the opening 30 therein.

An angle shaped bracket33 ,of non-mag netic material with the foot 34,extends from 7 the wall 20, and the foot3l of said bracket bears against the inner face of the wall 20, and is fastened thereto by the screw 35. A second angle shaped bracket 36 of non-magnetic material is indicated with the foot 37. The latter foot bears against the inner face of the wall 20 and is fastened thereto by the screw 38. An opening 39 is also formed in the wall 20, to secure the frame in place, I

' fastened to the bracket 36.

A wire 84 has one end "fastened guide flange 40: is formedinthe wall 20 having anopening 41 therein.

An electro-magnet 42 is indicated with its PATENT F-n ee.

core and the latter is supported in the 1' brackets 33 and 36. Apairof binding posts 45 and 'extend from the wall 20. "Acontact post 51 is indicatedwith the-contact I piece 52 and the foot 53. The post 5l is fas--,

tened to the wall 20, by means of thescrew 54, and washers 55 and 56 insulate the foot 53 from the'wall 20. p f f A wire 60 leads from one end "of the winding of the electro-magnet 42 to contact post said winding to the binding post50. 1

U shaped body portion 64 with the clapper 65 and of non-magneticmaterial. in this inand the s firin cont-act member 73 with the b 7 contact piece'ft. A leg 75 of the arin LD is v Aknee shapedbracket ,7 'witlrtlieffoot 79 and table 80 is fastened to the wall 20, by

A wire 62 leads from the other end of 7O 1 A reciprocating armature is indicatedin. its entirety by the letter B andcomprisesthe means of thescreWSL. A gong 82 [is suported onthe'table 80 by means-Of i c e "83 a d C vers the armature B; a a

. j exa bindingpost 45 and its other end is connected to a source] of electric current 8 5 l fA w re 86 has one end connected to the source of electric current and its other endis connected to the switch 87 and a wire 58 connects the switch 87 and the binding post 50. To operate the bell, the switch 87 is closed, and an electric current flows through the electro-magnet and magnetizes the core 43, by virtue of which the turned up ends 67 of the armature B are moved in the direction of the arrow F, and the clapper 65 strikes the gong 82. When the turned up ends 67 are brought close to the core 43; contact is broken between the contact same cycle is repeated.

clapper 65 continuously strikes the gong 82 pieces 52 and 74, by reason of the lug 68.

of the armature B bearing on the arm D, and the electric current is thereby interrupted. Immediately thereafter the tension of the resilient arm D forces the lug 68 with the armatureB in a direction opposite to the arrow F, and the contact pieces 52 and 74 again come in contact and the electric circuit is again closed, whereby the clapper 65 again strikes the gong 82 and the By this means the when the electric circuit is closed.

,VZLIIOUS modifications may be made in the lnvention and this exemplilication thereof is I to be taken as illustrative and not limitative 2. In an electric .bell the combination of a frame, a pair of brackets of non-magnetic materlal extending from the frame, an electro-magnet fashioned to one of sald pan of .brackets, the core. of said magnet extending beyond the ends of the coil thereof,an armature member "with a body portion of non-magnetic material and having a clapper slidably supported adjacent to the electro-magnet, a U shaped member with upturned ends of one piece of magnetic material extending from the body port-ion of the armature member, said upturned ends coacting with the core of the electro-magnetto be attracted thereby, a gong inthe path of the clapper and a resilient arm with one end fastened to the second of said pair or brackets of non-mag- .neticmaterial that extend from the frame,

a portionof said arm always in contact with said armature member and its swinging end in normal contacting engagement with a stationary contact whereby when the armature member is moved toward, the core of sald magnet that extends outside of the COll thereof, the contact between the swinging secure by Letters Patent and claim of, an armature member with the body portion thereof of nonmagnetic material and having a ClEtDDt-Bl shdabl sun orted bea l l a y l P tween the frame and the electro-magnet, a

Ujshaped member with upturned ends of one p ece of,magnetlcmaterial carried by thearmature member, said upturned ends coacting with the 'core of the electro-magnet contact piece extending from the frame,-a

bracket of non-magnetic material extending from the frame, a'resilient arm with one end fastened to the bracket, a portion of the arm in permanent contact with said lug and a contact piece/on the swinging end of the resilient arm in the path of the contact piece of the contact post. I

In an electric bell the combination of a frame, can electro-magnet carried by, the frame, the core of the 'electro-magnet extending beyond the' e nds of the coil thereof, an armature member with the 'body thereof of non-magnetic material and having a clapper, slidably' supported between the frame and the electro-magnet, a U shaped member with upturned ends of one piece 'of magnet ic material carried by the armature member, said upturned ends coacting with. the core of the electro-magnet to be attracted thereby, a lug extending from the armature member, a contact post extending from the frame and electrically insulated therefrom, a bracket of non magnetic material extending from the frame, a resilient arm with one end fastened to the bracket, a portion of'said arm in contact with said lug of the armature member, the

swinging-end of the resilient arm in the path of the [contact post, a gong enclosing the armature member and inthe path. of said clapper and a source of electric current for. the electro-magnet.
